Customer benefits

3EB1 / 3EB4 silicone rubber surge


core design

Stable, safe and long lasting

• Design and excellent sealing system:

• No moisture ingress, no failures

• No voids = no partial discharges

• Safe overload performance:

• No shattering/splintering of the housing

• No ejection of internal parts – no damage to surrounding

equipment or injury to persons

• Silicone rubber:

• Hydrophobic

• Low flash-over probability

• UV resistant: no erosion or aging effects

• Self cleaning: diffusion transfer to pollution layers

• Self-extinguishing properties

MOV: metal oxide varistors
